Question

A bird is flying north with a mass of 2.5kg has a momentum of 17.5kg m/s at what velocity is it flying

Answer 1

Momentum = mass • velocity
v= 17.5/2.5
= 7 m/s

Answer 2

Answer:

v=7 m/s

Explanation:

momentum definition

The amount of movement or linear momentum is the product of velocity by mass. Velocity is a vector while mass is a scalar. As a result we obtain a vector with the same direction and direction as the velocity.

The magnitude of the momentum is calculated like this:

p=m*v  Formula (1)

where:

p: momentum  (kg*m/s)

m: mass  (kg)

v: velocity  (m/s)

Data

m = 2.5kg

p = 17.5kg m/s

Problem development

We replace the data in the formula (1)

17.5kg m/s = 2.5kg*v

$17.5 kg*\frac{m}{s} = 2.5kg * v$

$v=\frac{17.5 kg*\frac{m}{s} }{2.5 kg}$

v = 7 m/s
